How to use glass fiber mesh:
(1)The preparation of polymer mortar must be carried out by a special person to ensure the quality of mixing.
(2)Rotate the barrel counterclockwise to open, and use a mixer or other tools to re-stir the binder to avoid separation of the binder. Stir moderately to avoid quality problems.
(3)The mixing ratio of polymer mortar is: KL binder: 425# sulfoaluminate cement: sand (with 18 mesh screen bottom):=1:1.88:3.25 (weight ratio).
(4)After weighing the cement and sand in the measuring bucket, pour it into the iron ash tank for mixing. After stirring evenly, add the binder according to the mixing ratio and stir. The stirring must be uniform to avoid segregation and porridge. Water can be added appropriately according to workability.
(5)Water is used for concrete.
(6)The polymer mortar should be prepared as needed, and the prepared polymer mortar should be used up within 1 hour. The polymer mortar should be placed in a cool place and avoid sunlight exposure.
(7)Cut the mesh from the whole roll of glass fiber mesh according to the pre-required length and width, leaving the necessary overlap length or the length of the overlapping part.
(8)Cut it in a clean and flat place. The cutting must be accurate. The cut mesh must be rolled up, and it is not allowed to fold or step on.
(9) Make a reinforcement layer at the positive corner of the building, and the reinforcement layer should be attached to the innermost side, 150mm on each side.
(10)When applying the polymer mortar for the first time, keep the EPS board dry to remove harmful substances or impurities from the board cotton.
(11)Scrape a layer of polymer mortar on the surface of the polystyrene board, the scraped area should be slightly larger than the length or width of the mesh, and the thickness should be about 2mm. Polystyrene side.
(12)After scraping the polymer mortar, the mesh should be placed on it. The curved surface of the mesh should face the wall, and apply it from the center to the surrounding area, so that the mesh is embedded in the polymer mortar. The mesh should not be wrinkled. After the surface is dry, apply a layer of polymer mortar on it, with a thickness of 1.0mm, and the mesh should not be exposed.
(13)The length of the lap around the mesh shall not be less than 70mm. In the part that is cut off, the mesh should be repaired, and the length of the lap should not be less than 70mm.
(14)A reinforcement layer should be made around the door and window shoulders. The reinforcement layer mesh cloth should be attached to the innermost side. If the distance between the door and window frame skin and the surface of the base wall is greater than 50mm, the mesh cloth should be pasted with the base wall. If it is less than 50mm, it needs to be turned over. The grid cloth laid on the large wall should be embedded in the outside of the door and window frame and glued firmly.
(15)At the four corners of the door and window, after the standard mesh is applied, add a 200mmx300mm standard mesh on the four corners of the door and window, place it at a 90-degree angle to the bisector of the window angle, and stick it on the outermost side to strengthen: in the open angle Place a cover - a piece with a length of 200mm and a width suitable for the standard width of the window, and stick it on the outermost part.
(16)Below the first floor of the window sill, in order to prevent the damage caused by the impact, the reinforced mesh should be installed first, and then the standard mesh should be installed. Strengthen the mesh cloth to connect.
(17)The construction method of placing the reinforcement layer is the same as that of the standard mesh.
(18)The grid cloth pasted on the wall should be covered on the grid cloth that is turned over.
(19) The mesh is applied from top to bottom, and the reinforced mesh is applied first in the simultaneous construction, and then the standard mesh is applied.
(20)After the mesh cloth is glued, it should be prevented from being washed or impacted by rainwater. For the outside corners that are easy to collide, protective measures should be taken for doors and windows, and anti-pollution measures should be taken for the feeding port. Surface damage or pollution must be dealt with immediately.
(21)The protective layer should not be exposed to rain within 4 hours after construction.
(22)After the protective layer is finally set, spray water for maintenance in time. When the average temperature of day and night is higher than 15℃, it shall not be less than 48 hours, and when it is lower than 15℃, it shall not be less than 72 hours.
